Compound Semiconductor Technologies

Focusing on compound semiconductors which are the key materials for photonic devices covering ultraviolet to infrared and superior electronic devices indispensable for wireless and optical communication as well as power electronics, we are conducting research and development on semiconductor materials and their application technologies, as well as peripheral technologies.

Compound semiconductors are widely used in various application fields in which silicon devices cannot be used. Sumitomo Electric has developed a variety of materials as a pioneer in this field.

Making use of our technologies of bulk crystal growth, epitaxial growth, simulation technique, characterization and analysis, we are promoting research and development on high-quality, cost-effective solutions for application-specific needs as well as on challenges for new materials.

Product development and key technologies

Compound semiconductors are widely used for optical devices and electronic devices. In each of these areas, we work on technological development aiming at downstream products such as epitaxial wafers, devices and modules, based on our material and device technologies.

Material design technologies

In the past, material designs depended on experiment alone. However, we are now working on simulation technologies that will help us expand our total range of R&D, such as the first principle calculation and thermal-fluid analysis technique.

We anticipate various applications, such as the creation of new materials and the development of production process.

Green semiconductor lasers

GaN-based transistor

GaN also has excellent features as a substrate material for electronic devices. To make full use of its advantages, we have developed vertical transistors and now are conducting their evaluation. They are expected to surpass conventional silicon devices in switching speed and energy saving.

Development of semiconductor thin films

We are conducting research on the thin film growth technology of compound semiconductor crystals. Aiming at the application to near-infrared sensors for chemical imaging, light-emitting devices and advanced power Analysis of doped GaN transistors, novel thin film crystals are being developed using our nano-structural analysis.
